Afghanistan army veteran: 'It's upsetting to see our work go to waste'

A former British soldier has said his tours of Afghanistan and the 20-year military presence of foreign troops feels like work gone "to waste".

Dave Watson lost both legs and an arm in an explosion in Afghanistan in 2010.

Speaking to the BBC's Victoria Derbyshire, he described the Taliban takeover as "upsetting" and questioned whether the sacrifice made by him and fellow troops was worth it.
